' COMBINED WATER AND AIR HEATER.

Specification of Letters Patent.

Patented a is, rare.

Application filed September 5, 1914. Seria1No.8G0,373.

To all whom it may concern:

, Be it known that ll, JAMns S. Niorrons, a citizen of the United States, residin at Atlanta, in the county of Fulton and tate of Georgia, have invented new and useful Improvements in Combined Water and A r Heaters, of which the following is a specification.

The invention relates to a combined water and air heater, and has for its primary object to provide a device of this character yvherein economy in the consumption of fuel 1s attained by utlilizing a maximum number of heat units for raising the temperature of water and air,,which are subsequently utilized in any desired manner.

The invention accordingly consists of a heater such as a stove having therein a cendisposed dome of substantially conical form, and superposed hollow bodies forming water circulating spaces which are adapted to permit the water to circulate so that the products of combustion will thoroughly heat the Water and also the air about the said drum may become heated so that both the hot Water and air may be utilized for any required purpose.

The invention consists of the novel features, details of construction, and combination of parts which hereinafter will be more fully set forth, illustrated and claimed.

As shown in the accompanying drawing, the view is a vertical central section of the heating stove embodying the invention.

.Referring to the drawing in detail, 1 designates a heater of the type generally employed for consuming coal, and utilized for warming dwellihgs and like structures.

be of any construction, sign, or make, and is provided at its upper end with outlet nipples which are arranged diametrically opposite each other and have connected thereto the elbow sections of hot air conveyer pipes 2, which deliver the hot air to any points within a dwelling house or like structure, while formed centrally of the top of the heater is an opening 3 through which extends the nipple end 1 of a bellshaped dome 5 which is located within the heater in the upper portion thereof and is supported upon an annular flange 6 formed internally of the said heater, while connected to the nipple 4 is the smoke pipe 7 so that the spent products of combustion can be delivered from the dome through the pipe 7 to the atmosphere.

Within the upper portion of the heater is arranged an annular chamber 8 which is adapted to receive cold air at its lower end through an opening 9 in the body of the heater, and this air is heated from the products of combustion circulating through the dome, and thereafter conveyed through the pipes to the required points of use.

Supported within the heater is a conical- .shaped drum 10, which has its smaller end extended Within the dome 5, while its opposite end is located above the fire chamber within the' heater, While above the smaller end of the drum 10 is a hollow hood or cap 11 which is supported upon hollow legs or tubes 12 establishing communication between the drum 10 and the said hood or cap 11, the drum being designed to form a water circulating space 13 through which the water to be heated travels. Tapped in the outer shell of the drum 10 for communication therewith is a water ipe 14 which delivers water therefrom. he water traveling through the drum 10 is admitted through the legs 12 from the cap 11, to which is centrally connected one end of a coiled feed pipe 15,

the latter extending through the dome 5 so that its convolutions will be disposed concentrically without the same, while the other end of the pipe 15 is extended upwardly through one of the pipes 2 to the required point for receiving the water supply, while the pipe 14 is extended to the required point of use.

Within the drum 10 is a hollow spider 16, the limbs or arms of which are tapped into the inner wall of the drum for communication therewith, while communicating 'centrally with the spider is thelower end of a frusto-conical hollow core 17, from the upper end of which rises a hollow leg or pipe 18, the latter being tapped centrally into the bottom of the hood 11 so that Water from the hood will circulate through the core 17 and the spider 16 into the drum, the spider and core being directly within the zone of the products of combustion of the fire chamber of the heater, as -Will be apparent.

lln the operation of the invention, the products of combustion from the fire burnmg in the lower portion of the heater 1 pass upwardly through the drum l0 and impinge against the hood or cap 11 so that the said products of combustion are deflected within the crown or dome 5, thereby heating the water or other liquid passing through the drum and cap, as well as warming the air the hot water from the drum circulating through the coil'of the pipe is further utilized-to heat the air in the chamber 8,

with the result that a maximum percentage ofthe heat units from a given amount of fuel are utilized for heating water and air, such hot water and air being subsequently employedin any required manner.

vFrom the foregoing description, taken in connection with the accompanying drawing,

it is thought that the construction of the device will be clearly understood, and therefore a more extended explanation has been omitted.- y

Having thus described the invention, what is claimed as new is: p 1. A heater comprising a body formed with a fire chamber near its bottom and also having outlet flues rising from its top at diametrically opposite points thereof, a dome located interiorly of the body in the upper portion thereof to provide a-hot air chamber between the said dome and the body, a smoke flue rising centrally from the dome through the top of the body, a conical shaped drum within the body'above the firechamber and extended for a distance within the dome, a hollow hood above the snialler end of the drum and having depending pipes communicating therewith, a water.

plpe communicating with the drum, means for admitting air to the chamber and a coiled feed pipe disposed concentrically about the dome and having one end cena upper trally Connected to the hood and also having said pipe extended through one of the outlet flues. v V

2. A heater comprising a body formed with a. fire chamber near its bottom and also having outlet flues rising from its top at diametrically opposite points thereo dome located interiorly of the body in the portion thereof to provide a hot air chamber between the said dome and the body, a smoke flue rising centrally from the dome through the top of the body, a conical shaped drum within the body above the fire chamber and extended for a distance within the dome, a hollow hood above the smaller end of the drum and having depending pipes communicating therewith, a water pipe communicating with the drum, means for admitting air to the chamber, a coiled feed pipe disposed concentrically about the dome and having one end centrally connected tothe hood and also having said pipe extended through one of the outlet flues, a hollow spider located within the drum and having its arms tapped therein, and a hollow core connected centrally to the spidier and having communication with the hoo 3. A heater comprising a body formed with a fire chamber near its bottom and also having outlet flues rising from its top at diametrically opposite points thereof, a dome located interiorly of the body in the upper portion thereof to provide a hot air chamber between the said dome and the dome through the top of the body, a conical shaped drum within the body above the fire chamber and extended for a distance within the dome, a hollow hood above the smaller end of the drum and having depending pipes communicating therewith, a water pipe communicating with the drum, a coiled feed pipe disposed concentrically about the dome and having one end centrally connected to the hood and also having said ipe extended through one of the outlet ues," a hollow spider located within the drum and having its arms tapped therein, and a hollow core connected centrally to the spider and having communication with the hood, the said body being formed with an air inlet for the admission of air about the dome.

In testimony whereof I aflix my signaturein presence of two witnesses.
